Zehr JP, Carpenter EJ, Villareal TA. New perspectives on nitrogen-fixing microorganisms in tropical and subtropical oceans. Trends Microbiol. 2000;8(2):68-73.
New molecular and microscopic evidence indicates that the open ocean harbors a diverse range of novel free-living and symbiotic nitrogen-fixing microorganisms. Although the extent to which these microorganisms fix nitrogen is currently unclear, ongoing research indicates that they might make a substantial contribution to the open ocean nitrogen budget.
